While iny invention is psrtieuleriy adept ebie for use. in connection with the tire trunks heieinbeifore eirpiained, it is ohvions that there are many other avenues of use thereforwhich will present theniseives from time to time., und l would have it un dei'stood that do not desire to limit myn to the specific :ipllieati'on or use herein shown and described, l having elected to set :toi-th my invention in connection with s tire trunk to render s clear and comprehensive understanding thereof to those skilled in the art.

li shell now proceed to describe my in vention with reference to the accompanying;

drawings, und then point out more partie-uf beine' shown in eiie'azzement with the shoe. l

Fig. 3 is e side elevation, partly in seetion9 ett inv adjustable clamping deviee'.sl1oiving the operating lever or crank, and Fig. i is e view on the line -b of Fig". 3, showing in. dotted line the position sf the clamping members When lnockededoi-vn.

Referring now to the drhwings in deteii, in which iike characters of reference are empioyed to designate similar parts through out the several views, 7 indicates a spare shee which in the present illustration is mounted on the running-"board 8 of the body 9 of the vehicle, the shoe being locked in the usual supports 10.

11 is a tire trunk of the well-known type which is made of a size and configuration to fit within the shoe, as shown, and which is provided with a suitable lock 12 for protecting the contents thereof.

.Mounted on the periphery of the trunk 11.

and extending transversely thereof are the 'clamping or locking devices 13. One or more oi. these clainping devices may be used, but 1 have found it preferable to employ three which are positioned at approximately equi-distant points on the periphery of the trunk 11 as shown. By the employment of thisnumber of clamps the trunk is lirmly supported in position and locked against displacement or removal.

Each clamping device 13 comprises a plate or bracket 14 which isapertured at 15 so that it may be secured to the tire trunk by means of countersunk screws, rivets or the like. The ends of this plate are upset to provide the ears 16 which are apertured, and form bearings for the rotatable screw threaded guide 17 the ends of which are formed With shoulders 18 to facilitate assemblage of the parts, portions ot the ears 16 being cut off to permit the shoulder ends of the guide 17 to be operatively positioned therein. The screw threaded guide 17 is provided With right and left hand threads and is centrally supported in a bearing 19 positioned on the plate 14:. The shoe engaging or clamping members 20 are made of any suitable metal, preferably brass, or the like, and are of a configuration Which-will insure a positive grip of the shoe, the shape being one which will preferably follow the contour of the side Wall oi the shoe as shown. These clamping members :20 at their lower ends are respectively provided with internally right and left hand threaded bores 20, the threads of which are adapted to be engaged by the right and left hand threads ot the' uide member 17 for the purposes which will be hereinafter more fully explained: One end of this guide member 1'1" is formed with a squared shoulder 21 which is housed.V Withina recess formed by an outwardly directed ,iiange on the conti guous ear 16. This squared shoulder is adapted to be engaged by thekoperating crank or lever 22 which is provided i:with an opening so that it .may be keyed thereto, by which means the guide 17 is rotated 'within its bearings and the clamping members 20 caused to move toward and .away from each other thereon. l

When it is desired to position a tire trunk, provided with my improved clamping device, Within a shoe attached to the running board or other part of the vehicle, the guide 1'? is rotated by means oi the crank until the clamping members Q0 reach the limit of their outward movement assuming the positions shown in Fig. 3. As the lower ends Q3 of the clamping members Q0 are normally in Contact with the upper surface of the plate 1d which forms a bearing surface or track therefor, during the movement of the clamping members 20 to and fro on said plate, whereby they are maintained in operative position, it will be observed. that, as the clamping members reach the end of their outward movement, they will fall or drop to a position at relatively right angles to their clamping or operative position, as shown in dotted lines in Fig. 1. This is due to the' fact that the plate 1/1 is recessed or cut away at 24, adjacent to each oi the ears 16, so that no bearing surface is provided for 'the lower ends .if the clamping members at this point and they consequently pivot on the guide 17 when they 'reach this position.

1t will be manifest that when the clamping members 2O are in a collapsed position, there will be no ditliculty in positioning the trunk 11 relatively to the shoe 7 after which the clamping members 20 may be manually moved or thrown into position to be operated or adjusted by means of the crank actuated screw 17 so that they will approach each other and firmly and positively grip the side walls oi the shoe, the manner 1n which they are thus positioned being clearly shown in Fig. 2. When the trunk has been thus locked into place the operating crank is simply Withdrawn from engagement with the shoulder of the screw guide 17, and the shoulder bmiig countersunk within the housing formed by the extending flange ot the ear 16 makes it practically impossible tor any unauthorized person to obtain access thereto, 'unless he is provided with an operH ating lever or similar key.

l have described my invention with particular reference to the details of structure herein illustrated, but itis apparent that the same may be varied in different ways without departing from the spirit and scope oll my invention.

Having thus described my invention what I claim as new herein and desire to secure by Letters Patent is:

1. A clamping device, comprising a rotetable member, clamping members mounted thereon and arranged to swivel on said member on reaching their outer limits of movement and means independent of said rotatable member to rotate the same and actu ate said clamping members.

Q. In combination with a tire trunk and a spare shoe, said trunk being positioned within said shoe, a clamping device mounted on said trunk, said clamping device comprising a rotatable member, clamping membersmounted thereon and means tor rotaton lamotor vehicle, said trunk to saidshoe, said means compris# member-k stamping ing a rotatable ,guide members oppositely positioned thereon, and

means for rotatin said guide member to actuate said clamping members thereon, the

of said shoe,

lto

rotation of the guide member in one direction causing said clamping members to approach each other and grip the side Walis and in the opposite direction to recede from each other, vto permit the re" moval of the trunk from its position within the shoe, saidA 'clamping members being adapted to swivel on said rotatable member on reaching their outer limits of movement.

d. The combination with a motor vehicle of a spare shoe carried thereby, a tire trunk positioned Within said shoe, and means for looking said trunk to said shoe; said means comprising a rotatable member, a pair oiclamping members mounted thereon and removable means for operating said rotatable member,"the movement of said operating means in one direction causing said clamping -members to approach each other and grip the Wall of said shoe to firmly loelr said trunk thereto, and in the rever direction to cause said clamping members-to recede from each other an". out of Contact With said shoe to permit the removal of the trunk from its position Within said shoe, said `elamping members being adapted to swivel on said rotatable member on reaching their outer limits of movement. y

5. A locking device comprising a plate having upturned ears at each of its opposite ends, said'ears being apertured to provide bearing surfaces, a right' and left threaded guide member yrotatably monnted Within said bearings, clamping members opposltely thereon,

positioned on said guide member and threadl` ed .for actuation t ereby, means detachable from said gunde member :tor rotating the same and actuatingy said clamping members, and means for maintaining said clamping members inelamping position during ,the

:actuation thereof, said means becoming inmember on reaching a predetermined limit oi movement,

means for rotating eaidfrotatable member to aetuate said clamping .mem-

bers, and means for guiding the movement of said clamping members during the aetna'tion thereof,

7.1i clamping device comprising a rotatable member, clamping members mounted thereon, means for rotating said rotatable member to actnate said clamping members,

and means for guiding the movement of said clamping members during the actuation thereof, said means becoming ineffective when said ciamping members reach a prede termined sono relative to said rotatable member. A

8. A clamping device comprising a rotatabie member, clamping members mounted means'for rotating said rotatable member to actnate said clamping members, and means for guiding the movement of said ,clamping members during the actuation thereof, said means becoming ineieetive when said clamping members reach a predetermined limit of movement, to permit said clamping members to swivel on said rotatable member.

In Witness whereof l have hereunto set my hand in the presence of two subscribing Witnesses this lith day of November, 19?;3.
